Dies to Removal

So I have gotten a bit tired of playing infect at my lgs's weekly pauper tourney (actually they are considering a local ban on glistener elf and mutagenic growth, so I'm switching for politeness reasons, because it's hard to get tired of winning). Since I am playing red deck wins in every other format, I am going to keep the red train rolling. Here's my first pass, any thoughts? Sideboard not done yet, currently just 4 shattering sprees and 4 red elemental blasts.
[Deck]

4 furnace scamp

4 gorehouse chainwalker
4 gathan raiders

4 rift bolt
4 seal of fire
4 searing blaze
4 incinerate

Lands

You have to run Fireblast! I like a more burn heavy build overall (Lava Spike, Staggershock, Flame Rift etc) myself but if you are trying for more of a RDW style build Kiln Fiend is an excellent card.

Shattering Spree is Uncommon so you'll need to run Smash To Smithereens. Martyr Of Ashes is your best board wipe.

Life gain is a bitch in Pauper so Mono B is pretty unfair and U Delver is also a pretty bad match up. That said with a nuts draw you can beat anything

I was trying to avoid playing straight up burn, but you are probably right, there is not a compelling reason to actually run creatures (not counting goblin fireslinger and keldon marauders) other than in a kiln fiend based build, at which point I may as well go back to playing infect. I might actually try completely creatureless burn because it will blank a lot of cards in a lot of decks, but the efficacy of slinger and marauders is hard to argue.

I like Fireslingers a lot but I swapped them out for Staggershock recently (which is better against Infinity, Delver and MBD) as they were just not ever really doing much. I still have Marauders in there though

EDIT - that's a lie! I took out Slingers for Curse Of The Pierced Heart and Kiln Find for Staggershock as they both kept dying to MBD removal. I still lose to their life gain though

The best RDW list in pauper is Goblins but Black kinda hates them out of the format, I would recommend burn if you want to play MonoRed - I did well in the past even against 8-Post. with 8-Post gone now I figure it should be even easier to play now.
